Week 4 to 5
During the fourth and fifth week of pregnancy, your baby is still a tiny ball of cells that is starting to take shape. The fertilized egg implants itself into the uterine wall and begins to grow into an embryo. At this stage, the neural tube, which will eventually become the brain and spinal cord, starts to form. You can see a small bulge on the ultrasound image that represents the developing head and the start of the neural tube.
Week 6 to 7
By the sixth week of pregnancy, your baby is about the size of a lentil and has a distinct head and body. The arms and legs begin to form, and tiny buds appear where fingers and toes will eventually grow. You can see the heart beating on an ultrasound image, and the brain continues to develop rapidly. At the end of the seventh week, your baby is about half an inch long and looks more like a tiny human.
Week 8 to 9
During the eighth and ninth weeks of pregnancy, your baby’s facial features become more defined. The eyes move closer together, the ears move into their final positions, and the mouth and nose take shape. The fingers and toes separate, and the baby can move them. The baby also starts to develop reflexes, such as sucking and swallowing. By the end of the ninth week, your baby is about an inch long and weighs less than an ounce.
Week 10 to 11
By the tenth week of pregnancy, your baby is officially a fetus, and all major organs are present. The baby’s body is still growing rapidly, and the head is still relatively large compared to the body. The baby can make facial expressions, and the skin is transparent, showing the blood vessels underneath. By the eleventh week, your baby can move its limbs and even squirm around, although you won’t feel these movements yet.
Week 12 to 13
During the twelfth and thirteenth weeks of pregnancy, your baby’s body continues to mature. The digestive system starts to work, and the baby can swallow and excrete fluid. The baby also starts to produce urine, which is released into the amniotic fluid. The baby’s sex organs are fully formed by the end of the thirteenth week, although it may be too early to tell the gender on an ultrasound image.
Week 14 to 15
At fourteen weeks, your baby is about the size of a lemon and is covered in fine hair called lanugo. The skin is still translucent and will become more opaque as fat stores develop. The baby’s movements become more coordinated, and you may start to feel tiny flutters, known as quickening. By fifteen weeks, your baby can make facial expressions and even yawn.
Week 16 to 17
During the sixteenth and seventeenth weeks of pregnancy, your baby’s skeleton starts to harden, and the muscles become stronger. The baby’s skin has a waxy coating called vernix, which protects it from the amniotic fluid. The baby’s head is still relatively large, but the body is catching up in size. By the end of the seventeenth week, your baby is about five inches long and weighs around five ounces.
Week 18 to 19
By the eighteenth week of pregnancy, your baby’s movements become more pronounced, and you may be able to feel kicks and jabs. Your baby’s ears are functioning, and it can hear your voice and other sounds. By the nineteenth week, your baby’s fingerprints are fully formed, and the hair on its head is growing. Your baby is also starting to develop a sense of taste and can taste the amniotic fluid.
Week 20 to 21
During the twentieth and twenty-first weeks of pregnancy, your baby’s eyes start to open and close, and it can see light filtering through the womb. The baby’s skin becomes less transparent and takes on a more opaque appearance. The baby’s movements are becoming more coordinated, and it may even respond to outside stimuli, such as your touch or sound. By the end of the twenty-first week, your baby is about ten inches long and weighs around twelve ounces.
Week 22 to 23
By the twenty-second week of pregnancy, your baby’s lungs are starting to develop, and it can practice breathing movements. The baby’s body is covered in a white, waxy coating called vernix caseosa, which helps protect the skin from the amniotic fluid. By the twenty-third week, your baby’s taste buds are fully formed, and it can distinguish different flavors. The baby’s movements are becoming more complex and can include sucking, swallowing, and hiccupping.
Week 24 to 25
During the twenty-fourth and twenty-fifth weeks of pregnancy, your baby’s brain is developing rapidly, and the baby can dream. The baby’s eyelids are fully formed, and it can blink.

The baby’s hair is growing longer and may be visible on ultrasound images. The baby’s sleep-wake cycle is becoming more established, and it may even have a favorite position in the womb. By the twenty-seventh week, your baby’s brain is starting to control more of its bodily functions, such as breathing and body temperature regulation.
